This cover is substantially semi- Water inthe form of rain or a spray when sprinno kling the garden will not enterand the bait holder may, therefore, be placed wherever convenient.

The openings, indicated at 4, which are formed in the annular flange 2,are of considerable importance as they permit a free circulation of airthrough the base beneath the container A. Such circulation tends to keepthe container cool, thereby preventing crystallization of poisoned baitin the formof a syrup, solution or the like, and if a liquid solution isused evaporation thereof is substantially prevented. Any suitable formof bait may be placed in the container, whether it be in the form ofsyrup, liquid, powder or in any other form.

While certain features of the present invention are more or lessspecifically described, I wish it understood that various changes may beresorted to within the scope of the appended claims. I also wish itunderstood that the materials and finish of the several parts employedmay be such as the manufacturer may decide or varying conditions or usesmay demand.

' It should also be noted that due to the fact that the cover is readilyremovable it is possible to maintain the container in a sanitarycondition as with'the cover removed the container can be easily washedand scalded so that the syrup bait will not have any tendency toferment.

What I claim is:

1. A,bait holder comprising a dish-shaped containerfor the reception ofbait, a downwardly flaring annular flange formed on the edge of thedish, said flange forming a support and base for the dish, a covermember for the dish, means normally securing the cover against removal,and a plurality of openings formed in the base flange to permit a freecirculation of air to retain the container in a cool condition.

2. A bait holder comprising a dish-shaped container for the reception ofbait, a downwardly flaring annular flange formed on the edge of thedish, said flange forming a support and base for the'dish, asubstantially semispherical-shaped member forming a cover for thecontainer and extending downwardly over the flaring base flange, apluralitybf keepers formed on the base flange, and a plurality ofinterlocking members formed on the cover and engageable with the keepersto secure the cover against removal.

3. A bait holder, comprising a container for the reception of bait, anda flange on the container forming a support and base therefor, saidflange being provided with perforations to permit circulation of airabout the exterior of said container.
